Fireproof cable

Abstract

The invention discloses a fireproof cable. An insulating layer wraps a conductor; a waterproof yarn is arranged outside the insulating layer; a protecting sleeve layer wraps the waterproof yarn. Due to the fact that the insulating layer is arranged outside the conductor, a protecting effect can be well achieved; due to the fact that the insulating layer is made from magnesium hydrate, pungent smell is not caused during combustion, gas harmful to a human body is not generated, and the pollution to the air is reduced; due to the fact that the waterproof yarn is adopted, the cable is protected from being wet and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a fireproof cable. Background technique [0002] Cables are used in some harsh working environments, and there is a risk of fire in some places. In case of fire, the damage to the cable is quite serious. At present, many cables simply add a fireproof insulation sleeve in terms of fire prevention. In terms of performance, it is easy to burn, weak in flame retardancy, and weak in corrosion resistance. It is easy to release a large amount of toxic gas when burning, which pollutes the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a fireproof cable with simple structure and strong flame retardancy. [0004] For realizing the above object, technical scheme of the present invention is: [0005] The invention relates to a fireproof cable, in which an insulating layer is wrappe...
